@Tru-Cao-Dang How did you test the project? On store-version Monaca Debugger (found on AppStore/Google Play) or custom Monaca debugger? On store-version Monaca Debugger, there are only core Cordova plugin included. Any other plugins you add in your project won’t be included. For this reason, whenever you add any other Cordova plugins, you will need to build custom debugger from Monaca Cloud IDE so that it would include those plugins. For more information, please refer to:
